Hardrock Energy

ROCKWOOL Hardrock Energy is a patented unique  rigid stone wool slab for warm and ventilated flat roof systems. Hardrock max can be used for both concrete and metal structured flat roofs. High density top surface provides point load of 500PL and improved compression strength. This surface support for mechanical fastening is the greatest advantage for applications with the PVC or TPO roof membranes. Like all ROCKWOOL products it protects against fire; provides acoustic comfort due to its fibrous structure; is uniquely durable against all forms of weather and is only sourced from sustainable materials.

The industry promotes highly the use of non-combustible insulation in this application.
